SELECT Count(*)
FROM stu_empl_pers
WHERE site_id = 'DEXLER';
returns 22 records.
but
SELECT Count(*)
FROM stu_empl_pers a
WHERE a.status = 'A'
OR a.faculty = 1
OR a.staff = 1
AND a.site_id = 'DEXLER';
returns 691 records.It considers different site_id also.Can anybody elaborate on this?
WHERE a.status='A' or a.faculty=1 OR a.staff=1 AND a.site_Id = 'DEXLER';
(true/false or true/false or (true/false and true/false))
maybe this will be more easier to see what your WHERE statement mean
if one of ORs (except the one with AND) become true the record will be added to the result
think AND like multiplication operand in math it has priority over OR which can be considered like sum operand in math
2*2-1 = 3 Not 2
I need status=A and site_id='dexler'as mandatory
then, could you try this?
Select count(*) from stu_empl_pers a
WHERE (a.faculty=1 OR a.staff=1)
AND a.status='A' AND a.site_Id = 'DEXLER';
That's because the filter conditions are different. The OR will return all records abiding to both filter condition.
Maybe what you're looking for in the second query is;
SELECT Count(*)
FROM stu_empl_pers a
WHERE ( a.status = 'A'
OR a.faculty = 1
OR a.staff = 1 )
AND a.site_id = 'DEXLER'; <-- missing brackets
Where you're adding a second level filter (a.status='A' OR a.faculty=1 OR a.staff=1) to the first query.

I can't finish writing query to filter row by multiply ids. Here is query:
select distinct `storage_file`.*, `storage_tag`.`id` as `tid` from `storage_file`
inner join `storage_file_tag` on `storage_file`.`id` = `storage_file_tag`.`storage_file_id`
inner join `storage_tag` on `storage_tag`.`id` = `storage_file_tag`.`storage_tag_id`
where `storage_file`.`user_id` = 17 and `storage_file`.`deleted_at` is null and
`storage_tag`.`id` IN(13,17);
So the result is without group by statement is:
So.. I need result only with two records which contain tid 13 and 17
And when i replace "IN(13,17)" with storage_tag.id = 13 AND storage_tag.id = 17 - i get no records at all
How can i write subquery which will work like a + b but not a OR b ?
I'm not sure what you do exactly but it seams, that the distinct is not working as you expect, because you select "*" from storage_file, as there are different values in the columns of storage_file, the result is distincted but over all selected columnns and so more the two are selected.
You can replace
... AND id IN (11,22)
with
... AND ( id = 11 OR id = 12)
You need the parentheses because WHERE operator precedence rules are very simple.
Of course,
... AND id = 11 AND id = 12
never returns anything because the id cannot have two different values at the same time.
i have a table named cq500_all(to record diffrent doctor feedback)
now i want know counts when condition status is
field dr_1_finish and field dr_2_finish value is all fill 1
and
when field dr_1 different dr_2 (like dr_1=1 and dr_2=0,or dr_1=0 and dr_2=1 )
cause i want to know two doctors feedback counts (when different doctor's feedback on jpg)
for example image show CQ500-CT-1_36_08.jpg and CQ500-CT-1_36_09.jpg is match my select counts
it will be two (select counts result)
how to make the query on mysql?
You can count as
select count(*) as total
from cq500_all
where dr_1_finish = 1 and dr_2_finish = 1 and dr_1 != dr_2
You will got result in total
Pretty much just the way you've described it:
select *
from cq500_all
where dr_1_finish = 1 and dr_2_finish = 1
and dr_1 != dr_2
or (if dr_1 or dr_2 might not be just 0 and 1):
select *
from cq500_all
where dr_1_finish = 1 and dr_2_finish = 1
and ((dr_1 = 1 and dr_2 = 0) or (dr_1 = 0 and dr_2 = 1))
I have 2 my tables with data and 2 "not mine" tables (in ReferenceDB) where thing ID can be mapped to its name.
One of mine tables is orders with following important columns: charName, stationID, typeID, bid.
Another table has following important columns: transactionDateTime, stationID, typeID, person, transactionType
I started my head braking with idea how to find orders that doesn't have any records for them lately (e.g. given amount of days). But for beginning I set me a task just to find orders that has no records for them at all. For that I figured out LEFT JOIN see biggest query below.
An order for me is a combination of charName/persone + stationID + typeID + transactionType/bid so if actually one of those four changes it is different order then.
Problem is that transactionType can be "yes" or "no" and bid is 0 or not 0. So I cant or DON'T KNOW HOW to JOIN ON different data types. So logically I'd like to join on 4 columns like:
FROM ordersTable LEFT JOIN recordsTable ON ordersTable.typeID = recordsTable.typeID
AND ordersTable.stationID = recordsTable.stationID
AND ordersTable.charName = recordsTable.person
AND ordersTable.bid = recordsTable.transactionType
Clearly last string of above wouldn't work cause of different data types.
So for a moment I thought that I can do such query twice for bid=0 with transactionType="yes" and second time for bid != 0 and transactionType = "no" see my query below for 0/"yes" combination. But seems it doesn't works exactly as I'd like it to. because AND ordersTable.bid IN (0) AND recordsTable.transactionType="yes" in JOIN ON doesn't sem do anything. (As I do get results where bid=1)
SELECT invTypes.typeName, stastations.stationName, main.* FROM referenceDB.invTypes, referenceDB.stastations, (
SELECT ordersTable.charName, ordersTable.stationID, ordersTable.typeID, ordersTable.bid, ordersTable.orderState, ordersTable.volRemaining
FROM ordersTable LEFT JOIN recordsTable ON ordersTable.typeID = recordsTable.typeID
AND ordersTable.stationID = recordsTable.stationID
AND ordersTable.charName = recordsTable.person
AND ordersTable.bid IN (0) AND recordsTable.transactionType="yes"
WHERE recordsTable.typeID IS NULL
AND ordersTable.orderState IN (0) ) as main
WHERE stastations.stationID = main.stationID AND invTypes.typeID = main.typeID;
Questions:
Is it possible to tell mySQL to treat "yes" as 0 or vise versa? If yes how do I do it in my query? If no what would be my work around (to find orders that doesn't have records related to them)?
And possibly some one can suggset a query that will find orders that didn't have records within given amount of days?
Thank you in advance!
One way is to use the explicit comparisons:
((ordersTable.bid = 0 and recordsTable.transactionType = 'No') or
(ordersTable.bid = 1 and recordsTable.transactionType = 'Yes')
)
Another would be to use a case statement:
(case when recordsTable.transactionType = 'No' then 0 else 1 end) = ordersTable.bid
SELECT invTypes.typeName, stastations.stationName, main.* FROM referenceDB.invTypes, referenceDB.stastations, (
SELECT ordersTable.charName, ordersTable.stationID, ordersTable.typeID, ordersTable.bid, ordersTable.orderState, ordersTable.volRemaining
FROM ordersTable LEFT JOIN recordsTable ON ordersTable.typeID = recordsTable.typeID
AND ordersTable.stationID = recordsTable.stationID
AND ordersTable.charName = recordsTable.person
AND ((ordersTable.bid = 0 AND recordsTable.transactionType = 'yes') OR
(ordersTable.bid != 0 AND recordsTable.transactionType = 'no'))
WHERE recordsTable.typeID IS NULL
AND ordersTable.orderState IN (0) ) as main
WHERE stastations.stationID = main.stationID AND invTypes.typeID = main.typeID;
I have a table with 5 fields. Each field can store a number from 1 - 59.
Similar to countif in Excel, how do I count the number of times a number from 1 - 59 shows up in all 5 fields?
Here's an example for the count of occurances for the number 1 in all five fields:
SELECT SUM(pick_1 = 1 OR pick_2 = 1 OR pick_3 = 1 OR pick_4 = 1 OR pick_5 = 1) AS total_count_1
FROM tbldraw
Hopefully I made sense.
There was an answer here that had a solution. I think this is just a variation.
Step1: Create a numbers table (1 field, called id, 59 records (values 1 -59))
Step2:
SELECT numbers_table.number as number
, COUNT(tbldraw.pk_record)
FROM numbers_table
LEFT JOIN tbldraw
ON numbers_table.number = tbldraw.pick_1
OR numbers_table.number = tbldraw.pick_2
OR numbers_table.number = tbldraw.pick_3
OR numbers_table.number = tbldraw.pick_4
OR numbers_table.number = tbldraw.pick_5
GROUP BY number
ORDER BY number
How about a two step process? Assuming a table called summary_table ( int id, int ttl), for each number you care about...
insert into summary_table values (1,
(select count(*)
from table
where field1 = 1 or field2 = 1 or field3 = 1 or field4 = 1 or field5 = 1))
do that 59 times, once for each value. You can use a loop in most cases. Then you can select from the summary_table
select *
from summary_table
order by id
That will do it. I leave the coversion of this SQL into a stored procedure for those that know what database is in use.
The ALL() function, which returns true if the preceding operator is true for all parameters, makes the query particularly elegant and succinct.
To find the count a particular number (eg 3):
select count(*)
from tbldraw
where 3 = all (pick_1, pick_2, pick_3, pick_4, pick_5)
To find the count of all such numbers:
select pick_1, count(*)
from tbldraw
where pick_1 = all (pick_2, pick_3, pick_4, pick_5)
group by pick_1
I am working on a mysql query that will filter out certain occurrences dependent on how many rows are returned.
I am trying to filter out any support categories when the number of rows returned are 1, however leave the support category in when the result set turned is more than 1.
I originally had this idea however it seems as if it will not work.
SELECT stockmaster.description, SUM(salesorderdetails.quantity), stockmaster.categoryid as qty
FROM salesorderdetails, stockmaster
where salesorderdetails.stkcode=stockmaster.stockid
and orderno='5222'
group by stockmaster.description
HAVING CASE WHEN stockmaster.categoryid = 'S&M' THEN COUNT(*) >= 2 ELSE COUNT(*) = 1 END
Any help will be gratefully accepted.
Try this
SELECT *
FROM
(
SELECT stockmaster.description,
SUM(salesorderdetails.quantity),
stockmaster.categoryid as qty ,
COUNT(*) AS count
FROM salesorderdetails, stockmaster
where salesorderdetails.stkcode=stockmaster.stockid
and orderno='5222'
group by stockmaster.description
HAVING CASE WHEN stockmaster.categoryid = 'S&M'
) MAIN_DATA
WHERE MAIN_DATA.count >1
